What is the function of triglycerides?

Triglycerides primarily serve as a significant form of energy storage in the body. Composed of glycerol and three fatty acids, they accumulate in fat cells and are utilized when the body requires energy, such as between meals or during prolonged physical activity. This function of storing energy is essential for maintaining a balance in energy metabolism, supplying fuel when dietary carbohydrates are unavailable.

While triglycerides are part of some other processes, such as supporting the absorption of fat-soluble vitamins, their primary and most recognized role is energy storage. Understanding the importance of triglycerides in energy metabolism highlights their critical function in overall health and nutrition, especially in how the body manages energy reserves.
